POWER APPARATUS FOR `BALlNC-PRESSE-S.

SPECIFICATION forming part of Letters Patent No. 781,374, dated January 31, 1905.

I Application filed March 26, 1904. Serial No. 200,187.

T0 a/ZZ whom t con/cern:

Be it known that I, HARVEY DANIEL SMITH,

of Battlecreek, in the county of Calhoun yand State of Michigan, have invented certain new and useful Improvements in Power Apparatus for Ealing-Presses; and I hereby declare that the following is'afull, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of thisspecification.

This invention is an improved power apparatus especially designed for use in connection withbaling-presses, its object being to produce a powerful compression mechanism operated by belt-power; and it consists in novel mechanism whereby the compression mechanism (preferably a toggle) lmay be operated from a continuously-driven shaft and may be automatically caused to move the plunger in and out in proper times.

The invention will be clearly understood from the following description, in connection with the drawings, and I refer to the claims vfor summaries of the features and combinations of parts forwhich protection is desired.

In the drawings, Figure l is a side elevation of part of a baling-press, showing my improved power mechanism applied thereto. Fig. 2 is an enlargedcview of rthe friction drive mechanism. Fig. 3 is a top view of Fig. 2. Fig. 4 is an end elevation of Fig. l; Fig.l 5 is a detail view showing a modilied arrangement for returning the-plunger.

In the drawings, A and B are two parallel shafts suitably journaled upon the framework of the machine adjacent to the baling-chamber. These shafts are preferably intergeared by pinions A B, so `as to rotate in opposite directions, and may be continuously driven from any suitable motor by a belt A2, engaging a pulley A8 on shaft A. Intermediate the shafts A B and parallel therewithis a shaft C, journaled in suitable bearings on the main frame, the bearing C thereof farthest removed from gears A B being secured'to the frame by bolts and slots, so that it is capable of Aa slight lateral movement, suiiicient to bring the periphery of a large gear or friction-disk or wheel c into contact with one or the other of two gears or friction-disks a and respectively, secured on the shafts A B.

For the purpose of shifting shaft C to-move and hold disk c in contact with disk a or rocking cams D E are provided, located on the opposite sides of the box C and mounted on short rock-shafts D E', journaled in suitable boxes fiXed to the main frame, the rockshafts'D E' being provided with doWnwardlyi extending levers D2 E2, which are pivotally connected by a link D2, so that the levers may be simultaneously operated to shift cams D E simultaneously, and thus move boX C right or left, one cam releasing as the other pushes, and the cams are so constructed as to firmly hold the boxv vand shaft C in either adjusted position with disk c, contacting with disk a or has desired. The levers are operated by means of the rods E3 E2,n connected to lever E2 and actuated at the proper times, as hereinafter described.

On shaft() is keyed a sprocket-gear C2, from which motion is transmitted through sprocketchain F2 to a large sprocket-gear F ona shaft F, journaledin suitable bearings on the main frame, as in Fig. l, the sprockets F' being preferably fitted to a squared end of shaft F, as this gives greater strength than a key.

On shaft F is likewise secured a large chaingear wheel f, which actuates the draft-chain ger in the baling-chamber is actuated. The chain f is connected to a link or eye g at the elbow or knuckle g of the toggle, said toggle comprising the long member G and short member (or members) G', members G G being pivotally connected togetherat the knuckle g. Member G extends inward and is pivotally connected at /L to'a plunger H, which works in the feed -chamber H, while the shorter member G' is pivoted on the main frame at c' in advance of the shaft Fand below thek plane of the pivot It. When the shaft Fis rotated so'as to pull the upper run of the chain inward, it ydraws pivot g' toward shaft F, eX-

tending the toggle, and consequently forcing the plunger H inward, compressing the material in the feed-box and forcing it into the baling-chamber. (Not shown.) Preferably the disk or gear c is at this time operated by the smaller gear or disk ce on shaft A, so as to transmit power in most direct manner from the prime motor. As the toggle extends it moves the plunger more and more slowly, naturally; butgreater power is exerted thereby, and any desired pressure can be given by properly adjusting the pressure of the frictional contact between disks a c when frictiongears are used. Furthermore, as the plunger reaches its inward limit of movement the knuckle g of the toggle comes into line with the pivots /z el and will drop slightly below such line, as shown in dotted lines, Fig. l, thus positively locking the plunger in its inward position until the shaft F is reversed so as to retract the plunger.

I have shown two means or ways for retracting the plunger by contracting the toggle. In Fig. l a lever J is attached to the pivot z' of the toggle member Gr in line with said member, and the outer end of said lever is attached to the other end of chainf, preferably by an adjustable swivel-link J. Thus as the toggle-lever is extended lever J takes up the chain f as it is paid out from chain-gearf, and when the motion of shaft F is reversed (which is accomplished by shifting disk cinto contact with disk chain-gear f pulls lever J back to the position shownin full lines, Fig. l, and thus contracts the toggle and retraets the plunger I-l. In Fig. 5 'the lever J is dispensed with, and a chain-pulley f 2 is mounted on a bracket attached to the main frame just outside of the outermost position of knuckle g of the toggle-lever, when the plunger is retracted and the chain f is extended from the knuckle-eye g to and around chaingearf, back to and around chain-pulley f 2 and attached to an eye g2 on the knuckle g. In this case the toggle is extended, as above described, and is contracted so as to retract the plunger by simply pulling chain f backward over pulley f 2.

The cam-operating levers D2 E2 may be operated by hand, but I have indicated in the drawings means for automatically shifting them, and for this purpose a rod E4 is pivotally connected to the lever E2 and extends forward to a point adjacent to the knuckle g when the toggle is in its retracted position and has a hooked end E5, adapted to be engaged by a pin or lug g4 on member Gr when the toggle is contracted and plunger H fully retracted, so that the rod Efl will be pulled outward, thereby rocking cams D E and throwing disk c into contact with disk (t, reversing the direction of rotation of shaft F and starting the plunger inward. When the plunger has completed its inward stroke and its knuckle moves past the line between pivots i 7,', the member G engages the short arm e of abell-crank lever ef/,pivoted on the frame, and rocks the latter, and as the longer arm e of said lever is connected by a rod or link E to lever E2 the cams I) E are shifted so as to move disk c into engagement with disk resulting in reversing the motion of shaft F and thereby causing' the retraction of the plunger.

The operation of the power will be clearly understood from the foregoing description and the drawings, and I do not desire to rcstrict myself to the particular forms or dimensions of parts indicated in the drawings, as changes may be made therein differential'.- ing the appearance of the structure while retaining the essential features and advantages of the invention.
